The To this end my invention consists in cerinstrument here shown is provided with two tain pneumatic mechanism controlled by the independent groups of sets of reeds 23 and 24, perforated music-sheet, whereby the desired corresponding to those of a two-manual or- 95 end is attained in a simple and effective mangan, but has only a single keyboard, which is ner, as will be hereinafter particularly set used only when it is not desired to operate forth; and my invention also consists in certhe instrument by means of a perforated m utain novel combinations of parts and details sic-sheet. To enable the construction and ofconstructiomashereinafterfullydescribed, mode oi operation of this instrument to be roo 5o and pointed out in the claims. more clearly understood, shall in this de- In the accompanying drawings, ,Figure l is scription use the term manual to designate each separate group of sets of reeds. The recesses 36 of the pneumatics of the sets of reeds 23 of the first manual communicate with chanvnels 37, connected by means of pipes or passages 38 with chambers 40 in two long chests 41 41, forming a portion of the pneumatic mechanism controlled by the music-sheet perforations, there being a chamber 40 for each note. Each chamber 40 contains air under pressure, which passes through a port 42 from a chamber 43, extending the whole length ot' the chest 41 and connected by a suitable passage 39, Fig. 3, with the wind-trunk 29, so that when the parts are in the position shown in Fig. 6 an equal air-pressure will be maintained on both sides of the reed-valve-operating diaphragm-pneumatic 35, causing the reed-valve to remain closed by means of its spring 44.

The two long chests 41, which are exactly alike, are placed one above the other, as shown in Fig. 6, to economize space, and the partitions of the upper and lower chests which form the chambers 40 are arranged alternately or staggering for convenience in arranging the pneumatics and the chambers or passages leading thereto from the trackerboard.

The stop-valves 30 of the several sets of reeds are operated in the usual manner by means of lever-and-rod connections with draw stops or pulls 46, as shown in Fig. 3, whereby the compressed air may be admitted to the valve-chambers 31 of the several sets of reeds, so that one set alone or any combination of sets of reeds may be used together in a Well-known manner.

4S, Figs. 2 and 10, denotes the perforated music-sheet, which is wound from one roll onto another in the usual manner and passes over the tracker-board 50, provided with the usual ducts or passages 51, commul'iicating through pipes or passages 52 with the primary or controlling pneumatics 53, which control the valve-operating pneumatic mechanism by means ot which the reed-valves of the [irst or principal manual orgroup of sets of reeds 23 are operated in accordance with the musicsheet perforations in a manner which I will now describe.

The several mechanisms by means of which the reed-valves of all the notes of the rst manual are actuated being exactly alike, but one will be described.

The tracker-board 50, together with the music-sheet 48 and its carrying-rolls, is inclosed within an air-tight box or chamber 54, provided in front with a sliding glass door 55, which affords access to its interior when the music-sheet is to be changed, said box 54 being connected by a pipe 56, Figs. 3 and 4, with the wind-box 27, whereby it is'supplied with air under pressure, which enters the ducts 51 of the tracker-board when exposed by the passage thereover of the perforations of the m usic-sheet. Each duct 51 is connected with a passage 52, Figs. 2 and 6, at the end ot' which is a primary diaphragm-pneu matic 53,which is raised when the air is admitted to the passage 52. This diaphragm liftsa primary puppet-valve 60, which opens a port 61, leading from a chamber 62 of a long chest 63 into a chamber 64, the chamber 62 being connected by a suitable passage 22, Fig. 3, with the wind-trunk 29, and said chamber 62 extending the entire length of the chest 63, which is divided by partitions into the chambers 64, one for each note, each chamber 64 communicating through a port.- 66 with the open air. When the puppet-valve 60 is raised by the diaphragm 53, the port 66 is closed and the port 61 opened, when the compressed air in the chamber 62 will enter the cham ber 64 and thence pass by a pipe 67 into a passage or channel 68, containing a secondary diaphragm-pneumatic 69, which is then raised to lift the stem of a puppet-valve 71, placed within the chamber 40 of the long chest 41, when the upper disk of the valve 71 will close the port 42, and the lower disk of said valve will open a port 72, leading from the chamber 40 into the open air. This vents the cavity 36 through the channel 37, pipe 33, chamber 40, and port 72, when the pressure of the air in the chamber 31 will operate the pneumatic 35 and open the reed-valve 32 to sound the note, as required.

I will now describe the means by which any predetermined note or notes of any set or sets of reeds 24 ot' the second group or manual the stop or stops of which have been previously drawn on may be .sounded in connection with or without the corresponding note or notes of the reeds 23 of the principal or first manual, thereby enabling me to produce solo effects hitherto impossible in organs operated by means of a perforated music-sheet as heretofore constructed.

Each of the chests 41 is provided above its chambers 40 with a chamber 75, extending its entire length and connected with a passage 76 common to both and connected by means of a pipe 77, Figs. 5, 6, and 11, with a chamber 78 in a small box 79, placed within the wind-trunk 29, said chamber 78 com muuicating through a port 15 (shown in Fig. 3 and dotted in Fig. 5) with the free or open air and by means of a port or passage S0 with the pipe 77. The port 8O opens into the windtrunk 29 and is kept normally closed to the wind-trunk by the upper disk of a puppet- Valve S1, the stem of which rests on a diaphragm-pneumatic 82 at the bottom of said chamber, a chamber or recess 33 beneath said pneumatic being connected by a pipe 84 with a passage 85, connected by a pipe S6 with a chamber 37 in the long chest 63, as shown in Fig. 11, the puppet-Valve 3S of which is raised by a diaphragm-pneumatic 90, beneath which is a chamber or recess connected by a passage 91 with a supplemental duct 92 inthe tracker-board 50, adapted to IOO IIO

IIS

cancel register with supplemental perforations 93, formed in the music-sheet 46, Fig. 10, said perforations being arranged in line with or preferably slightly in advance of the melodynote perforations of the music-sheet representing the notes which it is desired to sound inthe supplemental manual either as solo notes or in connection with the corresponding notes of such set or sets of reeds of the principal manual as may have had their stops drawn on.

As soon as the air enters the supplemental duct 92 of the tracker-board it raises the diaphragm 90, which in turn raises the puppetvalve 88 and-allows the compressed air in the chamber 62 of the chest 63 to pass by the port 95 into the chamber 87 and thence to the diaphragm-pneu matic 82, which is then raised .to lift the valve 81, which closes the port to the free-air chamber 7S and opens it to the Wind-trunk 29, thus permitting the air from the latter to enter the pipe 77, from which it passes to the passage 76 and thence into the long chambers 75 of the two chests 41 41, which are thus filled with air under pressure Whenever one of the supplemental perforations of the music-sheet is caused to register with the supplemental duct of the tracker-board.

On one side of each of the chambers 40 is a chamber 98, Figs. 5 and 8, which communicates through an aperture 99 at its top and an aperture 100 in a slide 101, to be hereinafter described, with the air-chamber 75 ot the chest 41. Vithin the chamber 98 is a dia- Aphragm-pneumatic 102, Figs. 5 and 8, which when operated by the air from the chamber '75 causes a sliding pin 103 to swing the piv- -oted arm of a bell-crank lever 104 against the resistance of a returning-spring 105 into the -path of a collar 106 on the stem of the puppetvalve 71, which when raised, as previously described, swings the bell-crank on its pivot y108, Fig. 6, when its pivoted arm will act on a push-pin 109, which opens a spring-pressed valve 110, commanding a passage 111 from the chamber 40 to a chamber 112, which latter communicates through a pipe 114 with a channel 115, leading to the reed-valreeperating pneumatic 35 belonging to that particular note in each set of reeds 24 of the second or supplemental manual, and it will thus be obvious that whenever the valve 110 is opened by the means described the pneumatic-chambers 36, connected with the channel 115, will be vented through the pipe 114, chamber 112, passage 111, chamber 40, and port 72, when the corresponding reed-valve 32 of any set of reeds of the second or supplemental manual the stop of which has been previously drawn on will be opened to sound the note, as required. lt will thus be understood that. whenever the air is permitted to enter the supplemental duct 92 ofthe trackerboard by the passage thereover of one of the supplemental openings ofthe music-sheet the pivoted arms of all the bell-cranks 104 in the chambers 40 of the two chests 41 41 will be swung over the collars 106 of their respective puppet-valves 71, ready to act when said puppet-valves are raised, as before described.

The pivoted arm of the bell-crank 104 lies slightly above the level of the collar 106, as shown in Fig. 9, to prevent any liability of its catching against it when swung over by its pneumatic, and l therefore preferably make the lower disk of the puppet-valve 71 loose upon its stein, which is provid ed with a collar 120, which when the stem of the valve 71 is raised is brought inlo contact with the said lower disk to lift it at the same instant that the upper collar 106 is brought into Contact with the arm of the bell-crank 104 to open the valve 110, thus causing said valve 110 and the port 72 to be opened at the same time as is necessary to insure the corresponding notes ot' the iirst and second manuals being sounded simultaneously.

Each second-manual channel 115 is connected by a pipe 122, Fig. 6, with a channel leading to one of the reed-valve-operating pnenmatics of the pedal-base, (not shown,) the notes of which can thus be sounded in the same manner as those of the Second manual previously described, provided the stop of the said pedal-base has been drawn.

When it is desired to couple the second or supplemental manual with the rst manual in order that the notes of both may be sounded together in every instance, l employ a pneumatic-coupler consisting of two long slides 101 101, Figs. 6 and 7, which are fitted to slide in suitable ways at the bottoms of the chambers 75. 'lhese slides are connected at their outer ends by a plate 123, Fig. 7, having ears 124, to which is pivoted the forked end ot' a lever 125, fulcru med at 126 and connected through the medium of a series of bell-cranks, rods, and levers 127, 128, 129, 130, 131, 132, and 133 with a pull knob or stop 134. Each slide 101 is provided with a series ot' holes 100, which when the pull-knob 134 is pushed in register with the holes 99, Fig. 5, leading to the passages 98 andpneumatics 102, which swing the arms of the bellcrank levers 104 over the collars` 106. The slides 101 are also provided with a series of holes 135, alternating with the holes 100, and which when the knob 134 is drawn out to move the slides register with a series of passages 138, Figs. 5 and 6, leading to pneumatics 139, Fig. 6, one t'or each chamber 40 ot' the chests 41, the passages 98 being closed bythe same movement of the slides which opens the passages 13S. Each pneumatic 139 acts on api n 140,which bears against and opens the valve 110 to vent the second-'manual channel 115 as soon as the port 72 is opened by the rise of the puppet-valve 71. In order l hat the entire series otl pneumatics 139 may be supplied with air at the moment that the pullknob 134 is drawn out, an inlet-aperture 141 is provided at the end of the tracker-boartl, which connects with the supplemental opening 92, as shown in Fig. 7^, said inlet-aper- ICO IIO

ture 141 being normally covered by a valve 142 at the end of a bell-crank 143, fulcrumed at 144 and connected by a rod 145 with a bellcrank 146, fulcrumed at 147 and connected by a rod 148 with the lever 131, which is connected, as before described, with the pullknob 134, so that when said knob is pulled to actuate the slides 101 air will be admitted continuously to the supplemental duct 92 to simultaneously supply air to all of the pneumatics 139, whereby all of the valves 110 will be instantly thrown open, so that whenever a puppet-valve 71 is raised to open the port 72 the corresponding note of the second manual will be sounded. It will be obvious that as the holes 99, leading to the pneumatics 102 for operating the swinging arms of the bellcranks 104, are closed at the instant that the passages 13S, leading to the pneumatics 139, are opened the swinging bell-crank arms will not be moved into the paths of the collars 106, but will remain at rest, the valves 110 having been opened by the pneumatics 139, the reason for opening the valves 110 by the pneumatics 139 instead of by the bell-cranks 104 being that if all the bell-crank arms should be swung simultaneously some of the puppet- Valves 71 would probably be in raised positions, so that some of the bell-crank arms would be swung beneath their collars 106 instead of above the same,as is necessary, which would cause the disarrangement of the mechanism, and many of the notes would sound continuously.

If desired, the organ may be provided with an additional or third manual, in which case it would merely be necessary to provide said third manual with pneumatic mechanism precisely the same as that employed for the second manual, the swinging bell-cranks of the third-manual mechanism being placed within the chambers 40 and operated in the same manner as those 104, previously described. This third-manual mechanism would be connected with another supplemental duct or passage 154 in the tracker-board, preferably placed at its opposite end, and with which would register supplemental openings 150 at the right-hand edge of the music-sheet, as shown in Fig. 10. ln this music-sheet the accompaniment-note perforations 16 are preferably arranged a little in advance of the melody-note perforations 17 for the second manual and the melody-note perforations 18 of the third manual, while the supplemental perforations are preferably arranged to register with the corresponding supplemental tracker-board duct an instant before the melody-note perforatio ns reach their ducts in the tracker-board in order to insure the bell-crank arms 104 being` thrown into the paths of the collars 106 before the puppet-valves 71 are raised, and by this arrangement of the perforations of the m usic-sheet the desired effects are produced in a most successful and harmonious manner. With an organ having` three manuals a flute-stop of the second maneinen-i ual could be drawn to be sounded with a certain melody-note 17 of said second manual by means of one of the supplemental perforations 93 on the left-hand side of the music-sheet, and a horn-stop of the third manual could be drawn to be sounded with another melodynote 18 of said third manual by means of one of the supplemental perforations 150 on the right-hand side of the music-sheet, as clearly shown at the top of Fig. 10, where the dotted lines indicate the notes with which the supplemental perforations at the opposite edges of the music-sheet are employed.

The music would usually be cut with supplemental perforations on each side, as shown, to adapt it for use with athree-manual organ in order to save the expense of making special arraugements of the same piece of music for both two and three manual organs, and to avoid this and enable three-manual music to operate a two-manual organ l provide the tracker-board of a two-manual organ, such as is here illustrated, with a crossover pipe or passage 153, Figs. 2 and 12, extending lengthwise over the tracker-board and connecting the supplemental passage 92 with the other supplemental passage 154 on the opposite side of the tracker-board and adapted to register with the supplemental openings 150 of the music-sheet which are intended for use with a three-manual organ, and in this manner the supplemental openings 150 in the music-sheet can be made to act on the second manual in the same manner that they would on the third manual if used in a three-manual organ. In a three-manual organ, however, it will be obvious that the crossover-passage 153 would be dispensed with, as each set of supplemental openings in the music-sheet would coperate with its own supplemental trackerboard duct.

The instrument is provided with the usual keyboard, the keys 155 of which are adapted to actuate valves 156, Fig. 2, by means of which the channels 37 are vented to cause the reeds of vthe first manual to be sounded yin the ordinary well-known manner.

It will be obvious that by a proper arrangement of the pneumatic mechanism the organ can be operated under the exhaust system instead ot' by air-pressure, as previously described, and, if desired, the pneumatic mechanism may be operated under the exhaust system and the reeds or pipes by air-pressure.
